The new fluorescent bulbs have a higher color temperature with more
blue light causing the perception of being much brighter.

I don't care about "perception of being brighter", I just know that when
they do get changed out, you damn near have to wear sunglasses because it is
so bright.

That's because the rods of the eye are more sensative to blue light and
the human eye has more rods than cones.
